VEHICLE-WHEEL.

SPECIFICATION forming part of Letters Patent No. 431,334, dated July 1,1890.

Application filed fieptember 11, 1889. Serial No. 323,665. (No model.)

To all whom it may concern:

Be it known that we, GABRIEL JOSHUA DE CORDOVA and PERCY ALBERT ISAACS,both of Kingston, Jamaica, Vest Indies, have inready repair of thewheel, and to so construct the wheel that the tire will at all times betight.

To this end our invention consists in certain novel features ofconstruction and peculiar combination of parts, all of which will behereinafter fully described in the annexed specification, andparticularly pointed out in the claims, reference being had to theaccompanying drawings, in which- Figurel is a side View of a wheelembodying our invention, parts being shown in section; and Fig. 2 is across-sectional View of the wheel.

Referring to the drawings, 10 represents the box or thimble, which isarranged within a wooden nave 11 in the ordinary manner. Centrally ofthe nave 11 We form an annular recess 11, in which is seated a rubberband 12, the upper portion 12 of which projects beyond the nave 11 andforms an abutment for the inner ends of the spokes, said spokes beingpreferably cut to the form shown in the drawings,-their inner endsbearing against the rubber band 12.

To prevent lateral movement of the spokes we provide a flange 13, whichis driven upon the rear end of the nave 1]., the forward face of theflange being substantially flush with the rear edge of the band 12. Inconnection with the flange 13 we employ another flange 14:, the hub orsleeve of which is internally threaded at 1 1 to engage anexternally-threaded washer 15, secured to the forward end of the nave.

Between the side faces of the spokes and the flanges 13 and 14 we placerubber washers 16, the lower ends of which bear against the upper orprojecting portion 12 of the elastic band 12. By this construction andby seating the band 12 in a recess 11 in the nave it will be seen thatlateral spread or displacement of said band is entirely prevented, evenshould some of the parts become loosened by 5 5 dially outward, therebyalways presenting a strong cushion for the abutting ends of the spokes.

To serve as an additional means of securing said spokes in properalignment we pro vide their outer lower faces with coincident recesses,which form a continuous annular recess 17 in which are fitted metallicrings 17, said rings being held in position by the rubber washers 16.

From the foregoing construction it Will be observed that the spokes restupon an elastic center, and as they are held under continual pressure itfollows that any expansion of the tire due to heat or any contraction ofthe folly due to shrinkage will be compensated for by the outwardmovement of the spokes, such movement being caused by the elastic base.

Although not positively essential, we prefer to place rubber cushionsbetween the outer ends of the spokes, either at the points marked 3 orat the points marked 4 in Fig. 2.

Having thus described our invention, what we claim as new,and desire tosecure by Letters Patent, is-

1. 1n a wheel, the combination of a nave provided with an annular recess11, an elastic hand held therein and projected beyond said recess,spokes which rest upon said band,

and the flanges 13 and 14: for holding said go with an annular recess11, an elastic band 5 fitted in said recess, having a portion 12projected beyond said nave, spokes resting upon is compressed radiallyoutward, substantially said projecting portion, provided with coinciasand for the purpose described.

dent recesses in their lower outer faces, metal GABRIEL JOSHUA DEGORDOVA; rings fitted in said recesses in said spokes, PERCY ALBERTISAACS.
